Синтаксический строку в панд, где не разделителем

Question

Я просто разобран на веб-страницу с помощью панд:

r = requests.post("https://www.eigroup.co.uk/clients/auctions/fulldetails.aspx?auctionid=17999 ", params=payload) 


parsed_page = pd.read_html(r.text, attrs={"class": "table-search-result"}) 

(пример HTML разбираемый)

    <td colspan="2">

и я получаю следующее:

In [86]: parsed_page[1][0][1] 
Out[86]: u'Description Leasehold 2nd Floor Studio Flat Unmodernised Vacant Guide Price \xa3450,000 Plus Lot Number 2 Auctioneer Savills (London - National) Vendor Housing Association Auction Date 28 October 2014 Lease Details 125 Yr, commencing 01/01/2013 (GR.\xa3250.PA)' 

Проблема заключается в том, что я хочу иметь возможность извлекать описание, цену руководства и т. Д., Но нет никаких разделителей, и количество символов после этого является переменной. Не хватает ли ключевого слова, когда я разбираюсь?

Как я могу разбить их на новые столбцы?

Answer 1

Использование BeautifulSoup, как я рекомендовал в ответ на ваш последний question, вы можете разделить текст и сделать Dict:

from bs4 import BeautifulSoup 

soup = BeautifulSoup(html) 

s = soup.find_all("p") 
details = (ele.text.strip().split("\n") for ele in s) 

d = {} 

for det in details: 
    if len(det) == 2: 
     d[det[0].strip()] = det[1].strip() 

{u'Vendor': u'Housing Association', u'Description': u'Leasehold 2nd Floor Studio Flat Unmodernised Vacant', u'Auction Date': u'28 October 2014', u'Auctioneer': u'Savills (London - National)', u'Lot Number': u'2', u'Guide Price': u'\xc2\u0141450,000 Plus', u'Lease Details': u'125 Yr, commencing 01/01/2013 (GR.\xc2\u0141250.PA)'}
